Abstract. Coleus barbatus Benth and Ocimum basilicum L. are plants species commonly used for medicinal and gastronomic purposes, respectively.
Caterpillars of the Spodoptera genus are generalists due to the wide variety of plants species used as food souce. The aim of this research was record
the occurrence of Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) in Sinop, Mato Grosso State, Brazil, and also record C. barbatus and O.
basilicum as potencial host plants for this insect species. It is recommended attention in inclusion of S. cosmiodides in Integrated Pest Management
(IPM) of this plant species.
Keywords: New occurrence; host plant; pests.
Coleus barbatus Benth e Ocimum basilicum L. (Lamiaceae): Novas Plantas Hospedeiras para
Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) em Sinop, Estado de Mato Grosso, Brasil
Resumo. Coleus barbatus Benth e Ocimum basilicum L. são espécies de plantas comumente utilizadas com fins medicinais e gastronômicos,
respectivamente. Lagartas do gênero Spodoptera são generalistas devido à ampla variedade de plantas que utilizam como recurso alimentar. O
objetivo desta pesquisa foi registrar a ocorrência de Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) no município de Sinop, Mato Grosso,
Brasil, e ainda, relatar C. barbatus e O. basilicum como potenciais plantas hospedeiras para esta espécie de inseto. Recomenda-se ainda a inclusão de
S. cosmioides em monitoramentos visando o Manejo Integrado de Pragas (MIP) nestas plantas.
Palavras-chave: Nova ocorrência; planta hospedeira; pragas.

he regions of biomes transitions are characterized by
presenting a great abundance of species from fauna and
flora. These areas present specific characteristics that
deserve more studies about behaviour and adaptations to local
changes. Sinop is a city located in the north of Mato Grosso State,
Brazil, in a transition region of Amazonia and Brazilian Savana
biomes.
Several insect species have been related and recorded in this
city, which extends the knowledge about the geographical
distribution, new host plants and their insect-plant relationship.
These informations are essential for ecology studies and also for
integrated pest management (IPM) programs.
The most recent literature about entomological biodiversity
in Sinop region were records on some insect species attacking
or feeding new hosts, such as Promecops claviger Hustache
(Coleoptera: Curculionidae) attacking soybean plants, Glycine
max Linnaeus (Fabaceae) (Barreto & Cavalet 2011); Leptoglossus
zonatus (Dallas) (Hemiptera: Coreidae) attacking Averrhoa
carambola Linnaeus (Oxalidaceae) (starfruits), Magnifera indica
Linnaeus (Anacardiaceae) (mango), Malpighia emarginata
Sessé & Moc. (Malpighiaceae) (acerola) and Morus nigra
Linnaeus (Moraceae) (black mulberry) (Pires et al. 2011, 2012);
Poekilloptera phalaenoides (Linnaeus) (Hemiptera: Flatidae)
attacking Sclerolobium paniculatum Vogel (Caesalpinioideae)
(Manica et al. 2012); Rhynchophorus palmarum (Linnaeus),
Rhinostomus barbirostris Fabricius, Homalinotus coriaceus
(Gyllenhal), Metamasius cinnamominus Perty, Metamasius
hemipterus hemipterus (Linnaeus) and Amerrhinus ynca
Sahlberg (Coleoptera: Curculionidae) on Cocos nucifera
Linnaeus (Palmae) (Dal Molin & Barreto 2012) and Costalimaita
ferruginea Fabricius (Coleoptera: Chrysomelidae) on Eucalyptus
sp. (Myrtaceae) (Pires et al. 2013).
Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae),
commonly known as velvet armyworm, is a species with a high
degree of phytophagy because it can feed on a wide variety of
plant species, such as peanapple, peanut, alfalfa, cotton, rice,
asparagus, potato, eggplant, oat, sugarbeet, coffee, caupi bean,
anion, cabbage, pea, crotalaria, sunflower, eucalyptus, apple,
mango, corn, sweetpepper, soya bean, tomato and wheat (Bertels
& Baucke 1966; Santos et al. 1980; Habib et al. 1983; Bavaresco et
al. 2001, 2004; Pastrana 2004; Specht et al. 2004).
This paper aimed to record the occurrence of S. cosmioides
in Sinop, Mato Grosso State, Brazil, besides to increase the
informations about new host plants for this insect species. Eggs,

Coleus barbatus Benth and Ocimum basilicum L. (Lamiaceae)…
caterpilars and pupae of S. cosmioides were collected in June
2012 on Ocimum basilicum L. (Lamiaceae) (basilicum plant)
and Coleus barbatus Benth (Lamiaceae) (Indian coleus), in a
transition region near by the urban area of Sinop and some areas
used for soybean and corn crops (11°51’11,15”S; 55°32’12,21”W
and 372 m above sea level). Ocimum plants present high levels
of some components frequently used in the pharmaceutical
companies (Morales & Simon 1996) and strongly used for the
traditional medicine (Martins 1998), besides as spice and
condiments for sauces. The Coleus genus is commonly used
Pires et al.
analgesic and against hypertension and diarrhea (Coelho Netto
& Assis 2002). It is also used during treatments for glaucoma and
asthma because of the presence of forskolin, a drug used for these
treatments (Suryanaranan & Pai 1998).
Ten caterpillars of S. cosmioides were collected directly on the
plants and taken to the Laboratory of Stored Grain Pests. Then
they were fed with indian coleus and basilicum leaves until they
became pupae. After adult emergency they were fixed, labeled
and identified by Dr. Evaldo Martins Pires and confirmed

by a Lepidoptera specialist at USDA Systematic Entomology
Laboratory, Smithsonian Institution. His diagnosis confirmed
the species Spodoptera cosmioides (Lepidoptera: Noctuidae).
It is still important to observe that during the period of sample
there was no crop nearby that could serve as host plants for this
insect species. Probably this could happen because it was the
dry period of the year, without almost no rain and low humidity
levels, period not suitable for important crops, such as corn and
soybean. The information about new host plant for S. cosmioides
can be a characteristic of this species to disperse or adapt to
local conditions, searching for alternative food sources. Then,
C. barbatus and O. basilicum crops nearby or around soybean
and corn crops are not recommended because these plant species
may serve as a refuge and food sources for S. cosmioides when
the main crops are not present.
